The puddle has dried up for the Summer and even if we fill it, it is just getting slimy and icky. The birds were still doing their best to get some water out of the dried mud, so yesterday I dragged out last years broken bird bath and rigged it up for them to use instead. It took about 3 hours before they trusted it enough to try it out. Today it is a part of their universe and not at all scarey like it was the day before.
The birdbath started out full, however I think I am going to be heading out there again soon to refill it. The blackbirds are great at splashing the water all over the place and it makes it difficult for the sparrows to reach when they want a drink.
